Comprehensive and Detailed Explanation (HCIA-Cloud Computing aligned):
This statement is incorrect based on HCIA-Cloud Computing virtualization concepts.
First, KVM is not a pure paravirtualization technology. It is a hardware-assisted full virtualization solution that relies on CPU virtualization extensions. While KVM can use paravirtualized drivers (such as Virtio) to improve performance, its core architecture is hardware-assisted virtualization.
Second, KVM supports device I/O virtualization. Using technologies such as Virtio, KVM provides efficient virtual network and storage devices. This allows virtual machines to achieve near-native I/O performance, which is a key feature emphasized in HCIA training.
Because the statement incorrectly classifies KVM and wrongly claims that it cannot virtualize device I/O, the correct answer is FALSE.
